Application filed August 4,

To all whom it may concern:

Be it known that I, CHARLES R. SEYMOUR, a CltlZGll'Of the United States, and resident State of New York, have invented certain new and useful. iin'n'o'n-zments in BoX-Covering hlachines, of which the following is a specification.

This invention machines which are adapted to apply a covering of paper to the tops and bottoms of paper or straw-board boxes or the like, and has particularreference to the mechanism for controlling the movement of the shearing knife.-

An object of the invention resides in the provision of mechanically-actuatedmeans for controlling the movement of the shearing knife which operates to sever the paper from the supply strip.

A. further object of the invent-ion resides in the provision of a mechanism which wiil automatically raise the knife to its initial or inoperative position and which will be reset for asubsequent operation.

of Rochester, in the county of 'Monroe and relates to tnat class of A still furtherebject of the invention i'esides in so constructing the mechanism that it will be controlled upon a movement of the work table.

In the drawings Figure l is a side elevation of a portion of a topping machine with the invention applied thereto; i

Fig. 2 is a front elevation of the same;

Fig. 8 is an enlarged fragmental plan view :-howing the clutch shifting mechanism; and

Fig. d is a fragmental. side elevation of the clutch shifting mechanism, also disclosing the actuating camfor the same.

In the drawings, a portion of a topper frame 1 is illustrated, at the upper portion of which is, located astationary knife or abutment 2, over which the strip of covering paper is adapted to be drawn in its.

passage from the supply roll to the work table. For cooperation with this stationary knife is a movable knife 3, carried by a rock shaft a, and the movement of which toward 7 cushioned by a the stationary knife is, spring; 5.

In orderw that the operator may bring with a bifurcated portion'27.

end toan arm? of the knife-carrying shaft 1:, and atits lower end is pivoted at6 to a lever B, which latter is pivoted at 9 to a stationary casinglO which provides a slip port for certain of the operating mechanism. Therod 6 is provided with aturnbuckle 11, so that its effective length may be variedatwill, Thus, whenthe lever 8 is supported in its uppermost position, the

knife 3 will be held in its raised or inoperative positiom'and when'the support for the lever 8 is withdrawn, the knife 3 will be permitted ito fall and. coact with the stationary knife to. sever the covering strip. Any suitable, means may be provided for controlling the raising and lowering of the movable knife through this lever 8, the

vmeans here shown comprising a cam '12 mounted rigidly on a rotary shaft, 13 and through a suitable driving connection, such.

for instance, as a worm and worm. wheelv 18 cooperating with a worm 17 on the shaft 17, which is also 'joiuinaled in the casing 10, and is driven from a driving shaft 18 through the medium of. a suitable friction clutch. This clutch comprises a socket member 1.9 and a cone member 20, the former of which is pro ided with a belt pulley 21 through which power is transmitted. The cone member20 ofthe clutch is provided with a. grooved collar 22, which is engaged by pins, on a shipper lever 24. This shipper lever is'pivoted at 25 to a projection :26 on the casing 10, and at its upper end is provided The cone member "20 is normally urged toward the socket member 19 by a coiled spring 28 whichrncirclcs the shaft 17 and expands between the. collar 22 and an adjacent portion of the casing 10. A latch 29, which is pivoted atBO to an arm '31 and is'provided is in engagement with the plate 84-, the cone member 20 of the clutch is held outof engagement with the socket member 19, and consequently the latter runs idle and the shaft 17 is not actuated. The arm 31 to which the latch 29 is pivoted, is integral with a sleeve 35 which oscillates about a shaft 9 and with which the lever 8, previously referred to, is integrally formed. Thus, the latch 29 and the lever 8 will move in unison as and for the purpose to be hereinafter described. e

The work support, which includes the usual standard 37 and base 38, is supported by the frame 1, at 39 ant is adjustable vertically, and also horizontally in both trans Verse and lateral directions, in the usual manner, the same being held in its adjusted position by means of suitable locking devices &0 and 1. Hinged at 4-2 to the base 38 is 2 work table which wardly by springs as. Pivoted at to to a bracl-zet if) on the under side of the table i3, is a depending arm 4L7, which extends down wardly through an opening in the base 38 and is provided engaging with a of the base with plate 4:8 on the under face oo to limit the upward morementof the table $3. The arm 7, at a point below the stop 50, is connects with a lever which, as here shown, compi' a rock-shaft journaled in a bracket :"i l: on the frame 1 and having two arms and T he arm 5:2, with which the table 2 l9 connects is keyed to the shaft at so that it will rotate therewith, but be free to move longitudinally of the shaft, so that upon. the lateral. adjustment of thowork support and table, said arm may be moved or adjusted in like direction. A pivotal connection of this arm with the table 3m l here made by means of a clain inc dc vice which adjustably engages the arm at? through an elongated slot l9 tierein. The second lever arnn 52, on the shaft 53, is pivotally connected 1th a rod 58, which latter at its to the lat-ch Assuming" that the parts are in the positions illustrated in the drawings, the knife 3 will be in its raised. or inoperative posi tion and the loose pulley 2-1 will be running idly. When the operator desires to cause the knife to descend to sever the 1 er, it is only necessary for him to either press upon the box which is supported by the .ud which is being operated u on.

upon the table itself. A mc"em nt o th t ble nd onu with itsarins and a conscquen upward movement of the rod movement of'the rod .Tl:' 29 about its pivot 30 from the Thospring 28 operate to throw the cone inembe normally urged upa stop device 50 for the lughest lower end is pivotally attached clutch into engagement with the socket mem ber 19. This engagement will cause the rotation of the shaft 1? and, through the coi.n .ction between this shaft 17 nd the cam shaft 13., will cause the rotation of the cam 12 in a cou11ter clocl-:wi,se direction. immediately upon this cam moving, the projection 16 on the lever 8 will ride of the am face 14-. and drop over the face 15, and being; connected to the ll'lOVztlJlfi knife 3 by the rod 6, will permit the knife to drop under the action of gravity to the paper. The continued ncrement of the cam 12 will gradually raise thelever 8 and connected knife 3, until tne projection 16 on the lever reaches its initial position, that is to say, a position such as illustrated in Fig. i, where it is about to pass elf of the can] face 14:.

l Vhen the lever 8 moves downwardly upon being released by the cam 12. the latch 29 will be thrust forwardly and the hook 323 thereon will engage the plate in the new position the shipper lever 28%, and there fore, when the cam 12 again raises the lever 8 about its pivot, the latch will be rethe shipper lever, will move the same against the action of the spring 28 and effect the disengagement of the clutch members 19 and This disengagement of the clutch members occurs at such time that the cam 12 will stop its movement when the projection 16 on the lever 8 is located at substan 'ally point of the face 1st, as illustrated in F i. ()f course, it will be understood that after the depression of the table if, it should be released to permit the table o again rise, at which time the hook por tion of the latch 29 will drop on to the plate 5 upon the thrusting of the latch so that L ward, the hook will engage said plate.

it will therefore be seen that for the operator to cause the severing of the paper and the r setting of the knife, it is only necessary for him to depress the table The re mainder of the operation will be automatic and the knife will be reset for a subsequent operati n which takes place only when the table is zg'ain depressed.
